Post partum and pain during sex?!

Im 8weeks post partum and when my SO and I have sex it feels like he's hitting my insides and it hurts like a cramp right where my right ovarie sorta is. Could something have gone wrong with my healing? My ob/gyn doesn't share very well (ex: I went my last three months with obvious odd discharge and she refused to notice and the day I went into labor I had a different dr who said it was from a uti!) needless to say I m getting a new dr. But is this normal? Or could she have missed something?
